It consists, further, as an improvement in watches, in a combinedmovement-plate, casecenter, and case-back constructed from one piece andhaving its inner edge adapted to receive a front movement-plate, incombination with a front movement-plate which is adapted to fit over andengage with said edge, substantially as and for the purpose hereinaftershown.

It consists, further, as an improvement in watches, in a combinedmovement-plate, casecenter, and case-back constructed from one piece andhaving its inner edge adapted to receive a front movement-plate, andprovided with a rabbeted outer edge, in combination with a frontmovement-plate which fits over and engages with the said inner edge, anda bezel that engages with the rabbeted outer edge, substantially as andfor the purpose hereinafter set forth.

It consists, further, as an improvement in watches, ina combinedmovement-plate, case- W center, and case-back constructed from one pieceand having its inner edge adapted to 8) receive a frontn1ovement-plate,and provided with arabbeted outer edge,in combination with a frontmovement-plate which fits over and engages with the said inner edge,abezel that engages with the rabbeted outer edge, and a pendant whichfits into and is secured within a radial opening in the periphery ofsaid part, substantially as and for the purpose hereinafter shown anddescribed.

It consists, further, as an improvement in 0 watches, in a combinedmovement-plate and case-center constructed from one piece and providedwith an inner edge which is adapted to receive a front movementplate, incombination with a front movementplate which fits 9 5 over and engageswith said inner edge, and with a movement-train that is placed betweenand journaled within said parts, substantially as and for the purposehereinafter specified.

It consists, further, as an improvement in watches, in a combinedmovement-plate and case-center constructed from one piece and providedwith an inner edge which is adapted to receive a front movement plate,in combi nation with a front movement-plate which fits ever and engageswith said inner edge, a movement-train that is placed between andjournaled within said parts, and a dial which is superimposed upon saidfront movementplate and extends radially to or near the edge of thesame, substantially as and for the purpose hereinafter shown.

It consists, finally, as an improvement in watches, in a combinedmovement-plate and case-center constructed from one piece and having itsinner edge adapted to receive a front movement-plate, and provided uponits upper edge with a regulator index-scale, in combination with a frontmovement-plate which fits over and engages with said inner edge, a dialthat is superimposed upon said front movement-plate, and a regulator-armwhich projects from beneath said dial over said index-scale,substantially as and for the purpose hereinafter set forth.

In the carrying of my invention into practice, adisk of metal, A, ispassed through dies, and its edge a turned upward at an angle of ninetydegrees, as shown in the drawings, after which the exterior and interiorof said part are turned in a lathe, and within the outer corner of itsupturned flange a is formed an annular rabbet, a, for purposeshereinafter shown.

Fitted to the upper open side of the part A, which constitutes a caseback and center and a back movement-plate, is a front movementplate, B,that has any desired shape in plan View, and within its lower edge isprovided with a rabbet, b, that enables it to fit over and engage withthe inner edge of the flange a. Said plate B is secured in place by adowelpin, 11, at one side and a screw, W, at its opposite side, or byany of the well-known and usual means employed for such purpose.

Between the plates A and B are placed the parts 0 of a movement-train,which parts are journaled within said plates in the usual manner, exceptthat the pivot-openings do not extend entirely through said plate A. Thebalance-wheel D is journaled between said plate A and the ordinary cock,D.

Fitted upon the plate B is a dial, E, between which parts are the usualdialavheels, F, that carry the necessary hands, G, while over said dialis placed a bezel, H, which engages with the rabbet a and incloses andsustains a glass, 71, in the usual manner. The diameter of said dial issuch as to leave the upper edge of the flange a exposed when said bezelis removed, and at a suitable point upon said edge is formed anindex-scale, a", over which extends a regulator-arm, I, that projectsfrom beneath said dial, the arrangement being such as to enable themovement to be regulated whenever said bezel is removed.

A pendant, K, secured within a radial opening, rd, in the flange a, andthrough which may extend the usual stemarbor for winding the mainspringand setting the hands, completes the invention, in which it will be seenthat the flanged plate A performs the functions of a caseback, acase-center, a rear movementplate, and the pillars that usually extendbetween and hold in relative positions the front and backmovement-plates.

Having thus described my invention, what I claim is 1. As an improvementin watches, a combined movement-plate, ease-back, and caseeenterconstructed from one piece, substantially as and for the purposespecified.
